The problem with the Civilian is the tip is extremely thin. As a last ditch effort SD knife it only needs to work once. As an EDC it would need a thicker tip.
My newer VG-10 Civilian has a noticably thicker tip than the ATS-55 Civilian that I traded off last summer. However I would heed Spyderco's advice that it is truly a self defense knife and not a utility knife. Now if you're going to get the Superhawk you won't have many jobs that blade can't do. It is a horse of a Hawkbill Blade. I don't own one yet but I have handled them and they are built like a skyscraper. The Superhawk has truly taken Spyderco's Hawkbills to a completely newer and tougher level.
I would personally trust the smaller Spyderco Matriarch for all around use before I would the Civilian. I was lucky enough to snag a VG-10 MATRIARCH and that blade steel is great for utility use. But do keep in mind if you would happen to snap a blade on a Matriarch model your chances of getting a replacement blade are almost zero.
